Background and aims: The clean room is under the control of concentrations of airborne particles play an important role in the production of drugs and high-tech products. Clean air flow pattern in the room is one of the important parameters of particle concentration and distribution of air pollution and need to be accurately modeled. So in this study was to evaluate and simulate the flow patter...
We build upon the clean-slate, holistic approach to the design of secure protocols for wireless adhoc networks proposed in part one. We consider the case when the nodes are not synchronized, but instead have local clocks that are relatively affine. In addition, the network is open in that nodes can enter at arbitrary times. To account for this new behavior, we make substantial revisions to the ...
We present results of a lattice analysis of the B parameter, BB, the decay constant fB, and several mass splittings using the static approximation. Results were obtained for 60 quenched gauge configurations computed at β = 6.2 on a lattice size of 243×48. Light quark propagators were calculated using the O(a)-improved SheikholeslamiWohlert action. We find Bstatic B (mb) = 0.69 +3 −4 (stat) +2 −...
In this paper we explain how we teach generic programming to master students in computer science. Key concepts to transfer are the relation between plain types and their generic representation, kinds, and the function parameters corresponding to arrow kinds. We teach this successfully in three steps, we start with simple solutions, show why they fail and how a more sophisticated variant solves ...
New research efforts are trying to evolve the current Internet. With satisfying communication hardware, the intent is to switch to data oriented networks. In this new vision, data will be the heart of the architecture and protocols have to be changed to dial with this concept. Promising ideas are proposed up in order to develop clean slate design solutions. However, these propositions encounter...
The atomic structure of the (1120) surface of cobalt has been determined by LEED using six intensity spectra at normal incidence. The surface exhibits the truncated bulk structure with a contraction of the first interlayer spacing by about 8.5% with respect to the bulk value. Quantitative evaluation of the LEED spectra was done using Zanazzi and Jona’s and Pendry’s r-factors. The minimum averag...
